Abstract:Based on the hourly precipitation data at 7 weather stations in Qingdao and the reanalysis data of NCEP from 1981 to 2012,the temporal and spatial distribution features of short-time severe precipitation events from April to October are analyzed and the conceptual models of short-time severe precipitation in Qingdao are established. The results show that: there is no obvious variation tendency for annual short-time severe precipitation days in Qingdao. Short-time severe precipitation events frequently appear from April to October,especially in July-August. The diurnal variation of short-time severe precipitation shows that there are two peaks. The most active peak is between afternoon and evening, and the second active peak is in early morning. Jimo, Pingdu and Huangdao are the frequent occurrence areas of short-time severe precipitation in Qingdao, and Huangdao is the region where the continuous short-time severe precipitation events occur mostly. Six types of short-time severe precipitation conceptual models are established, including the westerly trough type, transversal trough type, cold vortex type, tropical depression type,northwesterly flow type, shear line type,and the westerly trough type occurs mostly.
